Background: Procrastination as a self-regulatory deficiency is considered as one of the main factors in several personal and interpersonal problems. Aims: The main purpose of the present study was to examine psychometric properties of the Pure Procrastination Scale (PPS) including internal consistency, test-retest reliability, convergent/discriminant validity, and construct validity. Mehtod: Four hundred and eighty seven students (263 girls, 224 bpys) were included in this study. All participants were asked to complete the PPS, Tehran Multidimensional Perfectionism Scale (TMPS), Ego-Strength Scale (ESS), and Mental Health Inventory (MHI-28). Results: Test-retest reliability and internal consistency of the PPS were examined at satisfactory levels. The PPS revealed negative associations with self-oriented perfectionism (p>0/001), ego- strenght (p<0/001), and psychological well-being (p<0/001), as well as significant positive associations with other-oriented perfectionism (p<0/001), socially prescribed perfectionism (p<0/001), and psychological distress(p<0/001). These results confirmed the convergent and discriminant validity of the PPS. Conclusions: Preliminary results of exploratory factor analysis confirmed a general factor for the PPS. Based on the results of the present study, it was concluded that the PPS can be considered as a reliable and valid scale to measure procrastination in Iranian samples.
